Application filed September 9, 1910. Serial No. 581,127

To all whom it may con fi be equipped with draft attachments of any lie it known that I, CHARLES V. Gnnnns. 3 Suitable construction. Under the arrange-l a citizen of the United States of America, I

residing at Mound Valley, in the county of Labettc and State of Kansas, have invented new and useful Improvements in Disk Cuh iix'ators and llarrows, of which the following is a specification.

This invention relates to diskcultivat'ors, and it has for its object to produce an implement of this class which shall be capable of cultivating two or more rows of plants at each passage and which shall be simple in construction and efiicient in operation.

Vith these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of, parts which will be hereinafter fully described and particularly pointed out in, the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood 1 that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

In the drawings,-Figure tive view of a disk cultivator constructed in accordance with the invention. Fig. 2 is .a rear elevation of the same. Fi 3 is a side 1 is a perspec- 'elevation. Fig. 1 is a sectional detail view taken vertically through one of the disk cariymg standards and the disks connected therewith. Fig. 1s a vertical sectional view. taken on th "1 no 3 5' in Fig. 4. Fig. (3 is a perspectl l-taxl view showing the upper end of one of the standards and the adjusting washer detached.

Corresponding parts,in the several figures are denoted by like characters of refer ence.

The frame of the machine f omposcd'of a plank-1 of suitable dimensions having a forwardly extending tongue 2 and a forwardly extending bracket 3 which is connected with the tongue by means of a cross bar t. suitable braces being provided to reint'oree the construction, as shown at An evener (S has been shown pivotally connected with the frame bar 4. upon which it is adiustable by means of a pin or hammer bolt t which is connected with the main frame in r by a brace member 5. The cvener is to plank or beam 1,

mcnt shown in the drawing a three-horse equalizer isillustrated, but it is obvious that this arrangement" is subject to modification according to the size of the machine and the number of draft animals that are employed. Secured upon ,the underside of the beam or plank 1 are a plurality of pairs ofstandards B each comprising a shank 7 of cruciform cross section, said shank having at its upper end a headS and at its lower end a boxing!) wherein'a shaft 10 issupported for rotation, said shaft carrying at its ends the cultivating disks 11' which are of ordinary well known construction and of any suitable dimensions. The head 8 at the upper end of each shank is provided with a recess 12 having a cross bar 13 which an eye bolt 14. extending upwardly through one of a plurality said eye bolt being pro- 15 which'may be tight standvided with a nut ened for the purpose of securing the arcl firmly in position. The head standard is provided with upwardly the underside of the the purpose of establishing a.firm connection between said plankv and the standard. Fitted upon the eye bolt 1 is a wedge shaped washer 17 having a bolt en aging slot 18 enabling the said washer to e ad; justed laterally, thereby tilting the stand ard to any desired extent with reference to the beam or plank, it being obvious that the direction of they tiltmay be changed by is engaged by of perforations 15 in the of .the extends' 'ing teeth or spurs 16 adapted to bite into plank or beam 1 for},

changing or reversing the position of the washcr.= It is also obvious that by removing the washer, the standard may be secured in a position practically at right angles tothe beam or plank 1.

It is evident that when the standard is tilted, the cultivator disks carried by such standard willbe correspondingly tilted. It is further evident that by turning or ad-.,- justingthe standard about its axis each one of the disks carried by such standard may be set in advance of the other disk. Two disks carrying standards being employed for each row, it is further evident that the standards" may be adjusted so that the dirt will be moved either toward or away from the plants, as may be desired, and also that by properly tilting the standards, the device l may be fitted to operate upon a ridge when so desired, the. soil being moved in "either dijustments" may be very readily efilected by simply loosening the nut upon the bolt from the bolt without disassembling the parts said washer is preferably provided with a notch 19 extending from the slotjS to the edge o'l tl1e'washer,.said notch being dismsed intermediate the ends ofthe slot.

ing ofa centerbat-20 carrying a seat 21 and having obliquely disposed forwardly extending divergent side bars 22, the forward ends 10f which ,are hingedly connectedwith yokes "130*1jisingfromthe tongue 2 and the bracket 3, respectively. The frame bar 0 is provid'ed-witha foot rest 23in front-of the seat. Suitably connected with the truck bar 20 and supported for rotation is a vertical shaft 24 having at its upper-end an operating arm or lcvenQ-fgand atits lower end a rearwardly extending arm 2'6, can'ying caster wheel 27 Which trails in rear of the dish carrying standards and which serves to guide the .machine,. saidtrailing wheel being provided with an earth-engaging flange 28 for the purpose, of preventing side motion. It will be noticed that the Weight of the oporator isimposed upon the truck bar 20,

some distance in rear; of the supporting wheel, and the forwardly extending arms .22 which are hlngedly connected with the yokes 30 will thus exert an upward lift upon the tongue, thus relieving the necks of the draft animals 'of the Weight which would otherwise be imposed thereupon, and, accordingly,

facilitating the operation of the device to a large extent.

1 The operation and advantages of this invention will be readily understood from the foregoing description, taken in connection with the drawings hereto annexed. It is obvious that the device may be made of any desired dimensions to operate upon two or more rows of plants and that any desired numbertof' draft animals may be. utilined to draw? the machine over the field.

To operate upon each row, of plants two disk.

carrying standards are provided, each of said standards having a pair of disks, which by proper adjustment of the standards in the manner hereinafter described, may be arran 'ed to operatein the most advantageous manner with reference to the plants growi ng either upon level soil or at thefcrest of a ridge. The. desired adjustment may be made very easily and quickly by. simply loosening theflnuts 15' and adjusting the standardsan'd the washers 17 to 1; re desiredv position to. Which-the nuts are again tightened, the standards being retained with absolute security by one or more of the teeth or spurs 16 biting into .the underside of the I eases? beam}, The wedge-shaped Washers 17 may be readily removed when it shall be desired to anangethe standards approximately at right angles with reference to the supporting beam 1. 14. To enable the Washer 17 to berem'ovcd it is evident that the improved device,

while mainly described as a cultivator, nay be utilized as a barrow by properly ad usting the earth-engaging disks, or that an implement specially designed for harrowing the ground may be constructed on the lines designates a seat carrying truck consist of the-implement herein described;

Having thus described the invention, what is claimed as new, is:-1

1. In an implement of the character descrihed, a beam having aperturaa disk canrying. standard having upwardly extendingv spurs and provided with an eye bolt flexibly connected therewith and extending through an aperture-of the beam, aslotted wedgeening nut upon said 'oolt. 2. In an'implement of scribed, a beam having apertures, a disk oarrying standard having upwardly extending spurs,an eye bolt flexibly connected with the standard and extending through an aperture of the beam, awedgashaped washer having" a slotlengaging the eye bolt between the beam and thestandard and provided. with a notch-extending from the slot through the edge off the washer, and a tightening nut upon the bolt. v

3. In an implement of theqcharacter de scribed, a beanihaving apertures, a disk can rying standard having a bolt flexibly con nected therewith and extending through one of theapcrtures, a tightening nut upon the shaped washer upon the eye bolt, and a tight;
